Examination Sequence
The American Board of Medical Specialties (ABMS) instituted a policy for all 24 ABMS member
boards that limits the period an individual may be eligible for initial board certification to no
more than 7 years after completion of training. To comply with this requirement, the American
Board of Thoracic Surgery (ABTS or the Board) established the following examination sequence
for all candidates whose applications for certification are approved.
Prospective candidates are required to apply for board certification within 1 year of satisfactory
completion of an approved thoracic surgery residency program. Individuals whose applications
are approved must successfully complete the examination cycle to become certified in thoracic
surgery. The examination cycle includes Part I (Written) and Part II (Oral) examinations.
Individuals who apply for certification more than 1 year after the satisfactory completion of a
residency program would be considered individually by the ABTS Credentials Committee. These
individuals must complete any recommended additional training before they are eligible to
submit an application for certification.
Once an individual’s application is approved, they are declared a candidate and become Board-
Eligible for examination. They must then pass the Part I (Written) examination within 3 years from the date their application was approved. Candidates who successfully complete Part I
(Written) of the examination cycle must then pass the Part II (Oral) examination within the
succeeding 3 years from the date they passed the Part I (Written) examination. Candidates must
begin the examination process within two examination cycles from the time their application
was approved; however, if a candidate delays the examination process by one cycle it would
count against the 3-year examination requirement. (The Board STRONGLY recommends that
candidates apply for and, if approved, take the written exam in December of the same year they
complete residency training. ABTS data shows that candidates who delay their exam sequence
have a higher failure rate. If a candidate forgoes an exam opportunity, it would be counted as
one attempt of three available attempts. The Board does NOT recommend candidates forgo
exam opportunities.)
Candidates who fail an examination (Part I or Part II) are eligible to repeat the examination the
following year, for a total of three attempts in 3 years for each exam. Candidates have up to 7
years to successfully complete the Part I (Written) and Part II (Oral) examination cycle and
become certified from the completion of their thoracic surgery residency, without the
requirement of additional training.
Candidates who fail either Part I or Part II of the examination three times, or do not pass either
part of the examination within the allotted time period of 3 years, are required to complete
additional thoracic surgical educational training, which must be pre-approved by the Board. The
required additional training must be completed within the succeeding 2-year period after failing
either the Part I (Written) or the Part I (Oral) examination. Candidates who are completing
additional training will be considered “in training” and the Board’s eligibility rule will be on hold
until that training has been completed. Candidates who complete the required additional
training must have their eligibility for examination reviewed by the Executive Director and/or
the Credentials Committee prior to being permitted to retake the examination. Once readmitted
to the examination process, the candidate then has two more opportunities to pass the
examination (Part I or Part II) within 2 years.
Candidates who fail either Part I or Part II a fifth time are required to complete another
approved thoracic surgery residency program before they would be eligible to re-apply for
certification.
Candidates who pass Part I (Written) and Part II (Oral) and become certified in thoracic surgery
are issued a non time-limited certificate with a Milestone that must be successfully completed
every 5 years in order to maintain certification.
